Abstract

The inventive arrangement of bundles of fibrils in a part of a spin draw texturizing or draw texturizing machine presents a fan-type arrangement of these bundles of fibrils in which preferentially the longitudinal axes of the texturizing nozzles taking up the bundles of fibrils extend coaxially with a connecting line extending from a delivery point on a draw roll to the outlet of each individual texturizing nozzle.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. A system in a spin draw texturizing or draw texturizing textile machine for guiding bundles of fibrils through a texturizing devices comprising: 
       a texturizing unit including a plurality of texturizing nozzles, each said nozzle having a transporting portion and a texturizing portion in which said bundles of fibrils are texturized;  
       a pair of draw rolls with one of said draw rolls disposed to deliver said bundles of fibrils to said texturizing device; and  
       a false twist producing mechanism configured relative to each of said texturizing nozzles so as to produce a twist in said bundle of fibrils that extends from said false twist producing mechanism back to said draw roll, said false twist producing mechanism configured to produce a single direction twist so as to cause said bundle of fibrils to roll on said draw roll in a direction that increases tension in said bundle of fibrils between said draw roll and said texturizing nozzle until the increase in tension causes said bundle of fibrils to stop at a stable position on said draw roll.  
     
     
       2. The system as in claim  1 , wherein said false twist producing mechanism is configured directly with said texturizing nozzles such that the false twist extends from an inlet of said texturizing nozzles back to said draw roll. 
     
     
       3. The system as in claim  2 , wherein said false twist producing mechanism comprises air ducts disposed in communication with said inlet, said air ducts disposed at an angle and supplied with pressurized air so as to impart said false twist to said bundle of fibrils within said inlet. 
     
     
       4. The system as in claim  1 , wherein said false twist producing mechanism is disposed between said texturizing nozzles and said draw roll. 
     
     
       5. The system as in claim  1 , wherein said texturizing nozzles comprise an exchangeable element having said inlet portion defined therethrough, said air ducts comprising spiral ducts defined in said exchangeable element.
